First I want to say that I just got my Shield a week ago, after waiting months for the first batch to hit Costa Rica and 250 flawless rounds later, I couldn't be any happier with the way this gun performed. I am a new shooter, with tired eyes and had 10" groupings at 60ft. I like the way the gun fits my hand and I found the recoil to be less than I had anticipated. A friend just brought down my new holster for it Saturday and I love the combination of the Shield and my Latour holster. I also found out that while I was waiting for my holster to arrive, that I could pocket carry the Shield in an Uncle Mike's. This is not how I want to carry it, but was glad to see that I could. I am also grateful for this forum, that has given me a wealth of information over the last 6 months since I found it.
I didn't see a set specifically listed for the Shield on the Truglo website. My LGS didn't have a set for the M&P in stock, but said he has installed them on a few Shields. He told me they are a bit wider than the dovetail on the Shield and if you look close you can see it in the pictures above. He doesn't like the fact that the sight protrudes out of the dove tail a small amount on each side. I would prefer that it didn't, but for the gain that the sights give you, I think it's a small trade off. I ordered a set on line for $85 and if it really bothers me I will file each side of the sight to get a better fit. Strange that with all of the Shields hitting the streets, that Truglo hasn't reduced the width for a better fit on the Shield.
